Hydrostatic Density Measurement Scale KERN EMB 200-3V/YDB-01

The hydrostatic density measurement balance, consisting of the precision scale EMB 200-3V and the hydrostatic density determination kit YDB-01, is the perfect complete solution for gemologists, gemstone graders, and jewelry laboratories that require accurate weight and density measurements of gemstones.

With a readability of 0.001 g and an integrated density determination function, the scale delivers highly precise results - ideal for identifying gemstones based on their specific density. The density kit enables hydrostatic weighing, in which the stone is weighed both in air and in water. The scale then automatically calculates the density.

Density is one of the most important identification characteristics of a gemstone. Many stones share similar colors or refractive indices - yet their density often differs significantly.
With this set, density can be determined within seconds, as the scale features a graphically guided density mode that walks the user through each step of the process.

The density of a solid is calculated according to the Archimedean principle:
Density = Weight in air ÷ (Weight in air - Weight in water)
